This is my requirement:
I am creating a flow that should read messages from different queues.
I am not aware of queue name compile time/deploy time. I will only be aware of queue name at runtime.
so now I am using
SET OutputLocalEnvironment.MQ.GET.QueueName = 'myQueue';
could also use:
mqsiapplybaroverride can be used to control this deploy time.

Another name for this is "bar file override".
You can configure MQInput node at compile time, deploy time, but not at runtime.
Are you new to WMB ? This is a basic question.

MQGet is not an input node. It is a read node. MQGet node should not be used to begin a message flow.
Do you plan to attend training for WMB?

The MQInput node reads from a location that is fixed at deployment time.
You can *not* use MQGet node to start a flow.
There's no solid good reason to do what you want to do - there are several reasons that can be given, but they are meetable without doing what you want to do.
But you can still do what you want to do by using a TimeoutNotification node to run a flow every X seconds and then call something to decide what queue to read from and then call an MQGet node.
This is not a recommended practice. |

I am actually using timeoutnotification node to start flow, and then a mqget to browse from a set of queues.
I want to control how often messages are browsed, this is the reason for timeout notification, heartbeat approach.

If you attend the requisite training, you will learn the recommended approach.
Is there a reason you cannot attend the training?

Mqjeff indicates this is not recommended approach. Any hints on where to look for recommended approach. |
The recommended approach is to use mqsiapplybaroverrides to set the location that an MQInput node reads from.
You've resisted that, for no apparent reason.
You've resisted reading the documentation on the MQGet node to learn where it gets the name of the queue it reads from. For little apparent reason. |

Use two MQinput instances for two queues.Connect their out terminal to the subsequent node.
Hope it will solve your problem. |

Your internal processes may not support this. The product definitely supports this.
